How it works
This workspace starts at 500 KB (500,000 bytes). A 500 KB ceiling allows more data than the smaller presets, but busy photos can still need dimension reduction. Never enlarge a smaller file just to approach the limit.
- Choose a supported photo. The maximum size is already 500 KB.
- Keep the required dimensions if the form specifies them. Choose JPG or WebP when the destination accepts lossy images.
- Compress and check that the output is no more than 500,000 bytes. Review readability before downloading.
Supported files and limits
JPG, PNG, WebP, HEIC, and browser-decodable AVIF. Images are limited to 32 megapixels. Up to 40 MB per file; batches up to 20 files and 80 MB. Single-document operations accept one PDF.
Useful answers
Does 500 KB mean exactly 500,000 bytes?
FileFit treats 500 KB as a maximum of 500,000 bytes, using decimal KB. A smaller file meets this size requirement; no padding is added to make it larger.
Will every photo fit under 500 KB?
No. A 500 KB ceiling allows more data than the smaller presets, but busy photos can still need dimension reduction. Never enlarge a smaller file just to approach the limit. If fixed dimensions prevent meeting the limit, the result is marked as over the target.
What else should I check before submitting?
Check the actual format, pixel dimensions, orientation, and readability as well as bytes. A size limit alone does not describe every upload rule.
